Unison Spindle Repair
This Unison spindle’s bearings failed from contamination and loss of grease. The coolant jacket holds pressure and is not blocked up and the field tested good. We also noted that the machine-side electrical connector was broken off incoming and had spliced wires. We then measured the critical dimensions and noted that the front OD taper had 10-12µ runout. The rear housing was oversized +15/+18µ (ISO is 0/+11µ) and the front housing undersized -12/-20µ (ISO is +/-6.5µ), but we will use as is.
The following actions were performed on this Unison spindle:
- Clean, inspect overall dimensions
- Kiss grind front OD taper
- Replace bearings, wave spring, electrical connector, and assembly screws
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
